SOS; Monarch cat problem!
Comments (10)Tracey & Birdgardner, First of all, Monarchs do not 'discharge' any liquid prior to pupating. The discharging is something swallowtails do when they purge their systems prior to pupating. Monarchs do not do this and you should definitely isolate any caterpillar that has any unusual liquids coming out of either end. Green, runny liquid 'diarrhea' (scree) can indicate a variety of things: infection, poisoned/contaminated food, etc. Isolating the caterpillar, sterilizing all surfaces, and changing the food source are all advisable means to possibly saving the caterpillar. The reason you want to keep the caterpillar AWAY from others is that IF the larva does have an infection, the others can become infected if they eat leaves that have been touched by the scree (think about it: it is a way that the infection is spread). Personally? I euthanize all sick caterpillars. But, that's me. If you want to learn how to ID your caterpillar according to its instar, I do have some info on this on my butterfly blog. Good luck with you babies.

Comments (2)I put tape across the abdomen, looked at it under the microscope. No sign of any spores. The cats are inside at a relatively steady 70 degrees. I don't know the humidity indoors. Container has open mesh top to let air circulate. All are in their own containers. They were all taken from the outdoors a little later on -- not reared from an egg. Can't remember what instar they were, but probably 2nd or 3rd at the earliest. I didn't notice anything strange about the 2 recent caterpillars. The one I had a week before did exhibit signs of illness, and I figured it would die -- eating slowed down, started to droop head, then she'd "revive" and eat a little again. Then she pupated successfully. She only had a slight weakness upon eclosing, which was that she hung near the bottom of the enclosure as if she didn't have the strength to move up. Then she strengthened and flew around after a few days. I know there are lots of things that can affect monarchs, but I'm not familiar with more than a couple....See Morehelp!!! monarch cats keep dying!!!
Comments (12)Susan, As always my thoughts are my opinions based on many years of actually doing, not just accepting what others say. So they are only FWIW to be taken as a person chooses to take them. IMO common logic dictates that like with most infestation, disease or infection, the level they intrude an individual at can vary widely from minor to massive. That is commonly proved out with OE in Danaidae. If a larvae makes it through complete metamorphosis to an imago that can eclose and form OK, even if OE is present it was a relatively minor infestation in that individual. The opposite being if a larva at any instar, pupa or adult that has OE dies without getting through complete metamorphosis, that individual was obviously infested at a much higher level. Unfortuanately no matter at what level (with OE especially), failure to destroy any sick livestock whether it be OE, another parasatoid, viral or bacterial infection in most cases will promote the spread of any of any of them to other individuals. OE is the prominent one that will carry on to generation after generation beyond a given brood, and nothing but complete elimination of any brood within your control that might be infected with it will help slow it down in a colony. Why in my opinion when it comes to livestock even suspected of possibly having OE it's not worth taking any chances with them "for the good of the species as a whole". For those of use who did/do field work with Lepidoptera, that includes wild Danaidae livestock found or adults netted that show any possibilty of hosting OE. NOTE: Even if you have a very strictly controlled gardening and rearing rigime (which I doubt any of you have), you won't eliminate all of any OE present. So don't go slap happy destroying everything in sight. Instead be analytical and logical, and then decide what is reasonable for your own circumstances. Yes, livestock can have OE and not show any of the so called "visible" signs of it, which IMO are not proof positive of OE anyway and can be from other causes. In part why on my OE thread I offered some habit and condition factors that could also suggest OE is present as well even though they also do not prove OE and can also be from other causes. Bottom line, to prove OE is NOT present in an individual for certain takes a microscope or loupe. And in almost all cases if a larvae it will have to be euthanized to test with any certainty. A possibility to check for OE in pupa is to test the purge of the last instar larva for OE, but unforunately that is not 100%. I'm a lot more scientific in my appraoch to Lepidoptera than all of the folks here, so I don't accept things at face value. I am also skeptical of data from other sources that are not proven to me. The Internet and publications commonly breed misinformation about everything, including Lepidoptera, that is passed on by ACE's who probably got it from another one. So it's prudent not to trust every thing you read on the Internet or in books if it's not from a source you trust. Larry...See MoreThe 14 layer cake that wasn't
Comments (35)Got an update on the cake. The birthday girl loved it, thank goodness! She ended up taking it up to Chili's where they met some people for dinner. Apparently, the servers even got some as they were impressed with the layers. Carolyn said they came back and asked for a second piece to share with the other kitchen staff! And to top it off, one of Carolyn's friends wants to place and order with me for another cake. Thanks again guys for all the encouragement. Oh, and Joe, I'm still LOL at your compliments on my glasses and old pink apron. You made my day! Here's a pic Carolyn took of the cake after it was cut....See More- 8 years ago
